Cross-Linking Agents - Poly-Isocyanates

The Features of Our Polyurethane Dispersions for Textile Finishing

High-Performance Cross-Linkers

Chimica Lombarda’s poly-isocyanates are aliphatic cross-linking agents based on hexamethylene diisocyanate (HDI) and isophorone diisocyanate (IPDI), specifically designed for high-performance coating systems.

Chimica Lombarda’s hardeners are used in combination with polymers or binders containing hydroxyl groups or in two-component polyurethane coatings (PUR). The range includes low-viscosity and hydrophilic products for water-based bi-component coatings.
